Environmental Impact Assessment

Environmental Impact Assessment (EIA) is a process which identifies the environmental effects of a development proposal. You prepare a plan indicating the proposed location of your development, a brief description of the nature and purpose of your proposal and its possible environmental effects, including any mitigation measures. 

You will need to submit the EIA with your planning application and we will check that it complies with the Environmental Impact Assessment Regulations:
